The internal reflux distillation technique is based on a particular type of column which combines mass transfer and heat transfer, necessary for the fractionation of mixed vapours generated by boiling of a multi-component liquid mixture, in an equipment basically made of a number of vertical finned coils, internally cooled by a cooling fluid.
